GOODS CONTAMINATION AND EXTERNAL ATTACKS: MODELING VALUE CHAIN DYNAMICS IN RETAIL BUISNESS, Agostino Bruzzone, Matteo Mazzarese, Alberto Tremori
This paper focuses on modeling adverse events impact on retail networks; as crisis the model includes phenomena such as terrorism actions, contaminated or defective product lots; the model includes influence of media broadcasting news and customers fear. This research is based on the development of dynamic simulation to investigate hypotheses about the impact of various parameters and the response of different element of the retail supply chain.
THE PROBABILISTIC APPROACH TO THE DETERMINATION OF CONSUMPTION VOLUMES AND REPAIRING THE PIECES OF HYDROCARBON'S EQUIPEMENTS, H.Meglouli, E.Bouali
The system of hydrocarbon equipments maintenance includes a group of activities and organisional measures and techniquesThe principal equipment that ine ineet in the hydrocarbon domain consist of three parts: mechanical, electric and electronic and we are interested in the mechanical part which is related to the problems of planification of the repairing of the equipements constructive elements This research paper is devoted to the development of accomtancy approach to the problem of estimation or evaluation of consumption volumes and of pieces repairing, and equipments in taking into consideration the possibilities of the repeated renses of restored pieces and of samples heterogenrionsity of identical equipments at the time of repairingWe give at the end an application of the viewed approach to the case of installations of gas turbine
MODELLING OF MULTIMODAL FLOWS IN LOGISTIC USING OF NONPARAMETRIC METHOD, V.Jurenoks, V.Jansons, K.Didenko
In logistical process a great number of participants are involved and linked in a unified transport logistics system (TLS). The paper deals with the process of modelling of multimodal flows in logistic systems by using nonparametric method of research. The application of imitation modelling is connected with the fact that frequently it is not possible to provide a definite description of the behavior of the economic system being investigated. When investigating the dynamic behavior of the economic system, i.e. by making definite changes of parameters of the system under investigation, we frequently observe the existence of incidental factors affecting the character of behavior of the system. In addition, it should not be forgotten that the very character of the research also brings its incidental elements into the research process.
VEHICLE DISPATCHING WITH REALTIME LOCATION INFORMATION IN CONTAINTER TERMINALS, Xi GUO, Shell Ying HUANG, Wen Jing HSU
In container terminals with tight handling schedules, the transport between the quayside and the yard often holds the key to sustaining a high vessel rate. Thus the main objective of vehicle dispatching is to minimize the vessel turnaround time. However, because of the stochastic nature of the transport process, dispatching of vehicles is often far from ideal, resulting in a lower crane rate. To enhance the quality of decision for the deployment of the vehicles, mechanisms for inferring the vehicle job finishing time are needed. Moreover, improved algorithm for using the inferred vehicle locations is needed.
